﻿clone is good or not??

Research advances over the past decade have told us that, with a little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!

So, we can clone things, but why would we want to? Let's look at some of the reasons people give to justify cloning.

1. Cloning for medical purposes
Of all the reasons, cloning for medical purposes has the most potential to benefit large numbers of people. How might cloning be used in medicine?

2. Reviving Endangered or Extinct Species
Have you seen Jurassic Park? In this feature film, scientists use DNA preserved for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and fiercer than expected.

3. Reproducing a Deceased Pet
No joke! If you really wanted to, and if you had enough money, you could clone your beloved family cat. At least one biotechnology company in the United States offers cat cloning services for the privileged and bereaved, and they are now working to clone dogs. But don't assume that your cloned kitty will be exactly the same as the one you know and love. 

But I consider the full concept of cloning from cell to organisms, the benefits have enormous synergy with the other revolutions occurring in biology as well as in computer technology. As we learn to understand the genome of both humans and animals, and as we develop powerful new means of harnessing genetic information, cloning provides the means to replicate animals, organs, and cells. And that has profound implications for health and well-being, of both ourselves and our evolutionary cousins in the animal kingdom.
